Alliance Pharmaceutical Corp. (ALLP) Clinical Study Approved To Start In France

12/18/2006 11:21:05 AM

SAN DIEGO, Dec. 18 /PRNewswire-FirstCall/ -- Alliance Pharmaceutical Corp. today announces the approval from the French Competent Authority to allow the start of the Phase 2 clinical trial for Oxygent(TM) (perfluorochemical [PFC] emulsion) to prevent post-op ileus resulting from hypoxia during major surgery.

Earlier this year, Alliance reported that the French Ethics Committee (Investigational Review Board) had approved the start of the trial and that the French Competent Authority (regulatory agency) was considering Alliance's response to its review questions. That review has been completed and the approval was granted to start the trial. Alliance intends to begin the trial in the first quarter of 2007.

Alliance, through its contract manufacturer, is currently manufacturing the supplies needed for the above mentioned clinical trial, as well as those needed for its partner, Beijing Double-Crane Pharmaceutical Co. Ltd., to complete Double-Crane's submission to the sFDA and initiate its clinical development plan for Oxygent in China.

About the clinical indication for the Phase 2 Proof of Concept study:

During major surgery, the body often reacts by decreasing blood flow to intra abdominal tissues, thereby conserving blood flow and oxygen supply to vital organs, such as the heart and brain. As a result, gastrointestinal organs receive less oxygen and postoperative bowel function may be impaired.

PFC emulsions have been shown to improve oxygenation to organs and tissues. Clinical evidence for intestinal mucosal protection was obtained during an Oxygent Phase 3 study in which gastric tonometry was performed in a subset of patients at one clinical study site, measuring differences between carbon dioxide tensions in the arterial blood and those in the tonometer balloon (the "CO2 gap"). During cardiopulmonary bypass, control patients had elevated CO2 gaps and calculated intestinal mucosal pH statistically significantly higher than patients treated with Oxygent, in which these values were normal. This benefit translated into significantly shorter postoperative time to first bowel movement (2 vs. 5 days; p < 0.007) and a strong trend to earlier consumption of solid food (1.8 vs. 4.1 days; p = 0.056) (Frumento et al. Anesth Analg 2002;94 809-14). These clinical endpoints, time to recovery of upper gastrointestinal function (consumption of solid food) and lower gastrointestinal function (bowel movement), have been accepted by FDA, as approvable endpoints for Adolor Corporation's Entereg(R) (alvimopan) and Progenics Pharmaceuticals' methylnaltrexone for postoperative ileus associated with opioid analgesics.
